- Add validation to ensure the cipher suite in the ServerHello matches the one specified in the HelloRetryRequest.
- test_TLSX_CA_NAMES_bad_extension: use the same ciphersuite in HRR and SH
x509.c: realloc may fail and therefore need to store result in a
temporary so the old pointer is not lost.
tls.c: free the name if it is not pushed on to the stack of peer CA
names. Failure to push can be from memory allocation failure.
aes.c: Don't compile XTS decrypt functions without HAVE_AES_DECRYPT.
Fix tests to have better pre-processor protection.
